UNITED STATES CHARLES D. WHITE, OF NORWICH, CONNECTICUT.

THREAD CATGHER FOR, SPINNING FRAMES.

Application filed July 6,

T 0 all whom it may concern:

Be it known that I, CHARLES D. WHITE, citizen of the United States ofAmerica, residing at Norwich, in the county of New London and State ofConnecticut, have invented a certain new and useful Improvement inThread Catchers for Spinning Frames, of which the following is a full,clear, and exact description.

This invention relates to spinning mechanism, and more particularly to athread catcher for spinning frames.

An important feature of the invention comprises means, which is locatedbeneath the carrier roll of the spinning frame, and will function toreliably catch any thread passing over said roll to the bobbins, whichmay break during the spinning operation.

With the above and other important objects in view, the inventioncomprises the particular construction and arrangement of parts whichwill be hereinafter described. and will be pointed out in the appendedclaims.

Figure 1 shows, in front elevation, portions of the spinning mechanism,including the present invention;

Figure 2 is a detail view illustrating the bar with thread catchersthereon;

Figure 3 is an enlarged, detail view, of one of the thread catchingelements; and

Figure 4 is a view, partly sectional, at right angles to Figure 8.

The spinning frame may be of any desirec form, as for example, thatshown in United.

States Letters-Patent No. 1,448,984, granted to me March 20, 1923.

Such parts of the frame as are concerned with the present invention,comprise a bracket 3 having vertical slots 38 and screws or bolts 40 foradjustably clamping the bracket to the spinning frame for supporting asuitable number of bearings 15, for a carrier roll 9, and suitable pairsof draft rolls, one of which, 11, is illustrated in Figure 1.

The carrier roll 9 is provided with a plurality of circumferentialgrooves 10, which constitute guides for the thread as it passes from thedraft rolls to said carrier roll, and thence to the bobbins 7), locatedbelow the carrier roll. The grooves 10, I have found, perform verysatisfactorily the office of guides for the threads as they pass fromthe draft rolls, and said grooves require no extraneous devices upon thecarrier roll to 1922. Serial No. 573,104.

guide the thread, .passing the periphery of said roll.

The thread as it is being spun and laid upon the bobbins I) occasionallybreaks, and in order to catch the loose ends or broken threads I providea bar 5, preferably having reduced, polygonal or square, end portions 9,which enter openings of the same shape in the bearings 15, each bar 5being supported between two of such bearings. is equipped with aplurality of pins 7, best shown in Figs. 3 and 4, which may be passedthrough openings in the bar, and headed or otherwise enlarged at theirupper ends to secure them in said bar. The lower por tions of said pinsare provided with inclined slots 8, which face to one side of the frontof the machine. The bar 5 is located below, and somewhat to the rear ofthe center of the carrier roll 9, and opposite each groove 10 in thecarrier roll is located a pin 7. By this construction and arrangement ofparts I have found that when one of the threads which passes around agroove 10 breaks, the pin 7 with its slot 8 will catch the broken end ofthe thread and hold it until the thread can be repaired, in the usualmanner by one of the attendants whose duty i1 is to repair these brokenthreads.

It will be obvious that changes may be made in the details ofconstruction, or in the arrangement of the several parts shown, withoutdeparting from the spirit of this invention, provided such changes arewithin the scope of the following claims.

I claim: 7

1. A machine of the class described having, in combination, a carrierroll provided with a plurality of spaced grooves, a longitudinal barlocated below said roll, and pins provided with downwardly inclinedthread catching slots therein and projecting from said bar opposite saidgrooves.

2. A machine of the class described having, in combination, a carrierroll provided with a plurality of circumferential grooves, bearings forsaid roll, a bar located below and to the rear of the center of saidroll and having its ends secured in said bearings, and pins projectingdownwardly from said bar in alinement with said grooves, said pinshaving downwardly inclined thread catching slots therein.

In testimony whereof I have hereunto set my hand this 28th day of JuneA. D. 1922,
